Data Correlation and the Simpson Paradox

Summary Simpson’s paradox is a fascinating statistical phenomenon where the observed relationship between two variables can be reversed when the data is divided into subgroups. For biologists and biochemists, this means that the correlation between two biological variables might change direction when considering an additional categorical variable, such as a specific species or experimental condition. …
